9 Application filed August 7, 1917. Serial No. 184.820.

in an attachment for typewriting maehii'iesa and more especially toacollating device for assembling work-sheets to he written on atdifferent. relative points. This case is an improvement on myapplication. No. 180,530. filed July 14, 1917.

In the present case, the sheets are as sembled face upwardly at thefront of the platen on the collating portion of a paper 'arrlel' oreollatin; frame, which is main-' tained in a position wrapped around theplaten. and may he oscillated bac and forth by rotating the platen.

For the purpose of positioning the assembled sheets on the platen, andcarrying. them line by line in a normal typewriting operation. the framemay be provided with two series of studs. so that. the work-sheets.

which have corresponding openings in their side margins. may he impaledon the studs 'to properly position them relatively to each other and toth eollating} frame,

The \\'orl\'sheets. after they have been placed on the collating frame,are preferably utonaitically fed around the platen in a reverseline-space direction. by means of a spring connected by suitablemechanism to one end of the collating frame.

This automatic feed may he under the control of a finger-piece orreleasing key connected to the line-space detent and the feed rolls, lnder normal conditions. the automatic feeding of the platen may heprevented by the line-space detent and the pressure of the. feed rolls.

Automalically-operated means, controlled by an adjnstahlestop on thecollating frame, may be provided for limitin; the reverse feedingmovement of the collating frame withlthe work-sheets thereon to stop therotation of the platen when the tirst printing dine, Qt'the work-sheetreaches the printingpoint. 'lhis stop may he also etl ective to trip thefinger-piece or release key, so as to bring the feed rolls and detentinto play when the work-sheets have been properly positioned for printinThe collating frame is flexible andis guided around the platen in aU-shaped path. It may have in addition to the spring connected to itsone end for automatically feeding it around the platen,-an0ther springconnected to its other end; the power of which is less than that of thefirst spring,

and sutiicient to keep the collating frame taut. but not to counte'actthe action of said first. sprin".

The body portion of the collating frame may act as a backing" for thework-sheets. This frame is detachable so that it may be convenientlyremoved from the machine and replaced by another when the body portionbecomes worn, or damaged by the types.

Other features and advantages will hereinafter appear.

In the ata-(mipanying drawings,

Figure 1 is a perspective view, showing the collating frame in aposition to receive the work-sheets to be assembled.

Fig. 2 is a side ele 'ation, with the parts in the position of Fig. 1.,

Fig. 23 is a view similar to Fig. 2, except that the pressure feed-rollsand the line space mechanism detent have been released, so s to permitthe easy reversal of the collating frame and platen, for the purpose ofplacing the work-sheets on the platen after having been collated.

Fig. l is a view similar to Figs. 2 and 3, partly in section. thecollating frame having been moved downwardly at the front with areverse. rotation of the platen, so as to place thev assembledwork-sheets on the platen,

and the. stop carried by the frame having tripped the pressurefeed-rolls and line The platen 1 is mounted on the. usual platen axle 2,which, in turn. is mounted in an inner carriage or platen frame 3.platen 1 is rotated for a number of line spaces by the usual knobs 4provided on the The end of the platen. axle 2. It also may have theirreleased position avl'ien they line-space movements by means of alinespace mechanism, indicated n1 'eneral at 5,

andiucluding a linespace wheel 6. This mounted on swinging frames 12 and13, so.

as to be adjusted toward and from the platen '1,

Normally, the pressure feed rolls 10v and 11 are held. in intimateContact with the platen 1 by means of springs (not shown).

. To release these pressure feed rolls, there is provided a finger-piece14, which, when depressed, draws on a link 15 to rock a bell crank 16secured to a shaft 17. The shaft 17 is provided with reduced portions 18normally engaging their flat sides with arms 19 and 20', provided ontheframes 12 and 13 carrying the pressure feed rolls 10 and 11.

The rockin of the shaft 17 s )reads the arms ,7 h 19 and 20 apart,thereby withdrawing the pressure feed rolls 10 and 11 from engagementwith the platen 1.

The pressure feed rolls 10 and 11 can be released from another point,which also disengages the detent- 7" from the line-space wheel (3. Thisincludes a hand-lever 21, which, when depressed, pulls up on a link 22to swing upwardly a platen release 23 engaging the detent 7, Thisrelease forces the roll 8 out. of engagement with the teeth of 'theline-space wheel 6,

The release 23 is connected by a link 2i to an arm 25 on the rock shaft17. Thus, the hand-lever 21 can release the detent 7, and at the sametime rock the shaft 17 to release the pressure feed rolls 10 and 11. Thereduced portions 18 on the shaft 17' act to lock the feed rolls in i aoperated from thevfinger-piece 14 or t handlever 21. T his, also locksthe detent 7 in its release position, until either the hand-lever .2l.or the lingerpiece 1d is returned to its normal position.

For the purpose of asseml'iling sheets at ditlereut relative positionswith respect to each other, so that the writing may be reproduced onseveral sheets and on the proper lines on ditlerent sheets, there isprovided a collating frame or paper-carrier 26, which normally extendsaround the platen 1 between the platen and the pressure feed-rolls l0and '11. This frame is made of a sheet of dlexible material, which hasattached thereto a pair of collating strips 27, arranged to extendaround the platen at opposite ends thereof. These collating strips 2?are providcil with 'laper-holding means or collating studs upon which.the Workcollating frame 26.

have perforations on either side margin, or;

sheets 27 may be impaled to adjust them relatively to each other andrelatively to the T he work-sheets may if wide enough to stretch acrossthe frame, on both side margins, so that they can be placed over thestuds 28. It will he noted that the strips 27 extend around the platen 1in such a manner that the studs face to the front, and are located atthat end of the strip 27 which extends upwardly from the front of theplaten 1. This enables the work-sheets 27 to be impaled on the studs 28facing front with their leading edges uppermost.

Normally, a driver in the form of a spring 29 tends to hold or withdrawthe collating frame 26 to its starting position shown in Figs. 4 and 5.This spring 29 is connected to levers 30 and 31 forming part of anexpanding device having a lazy tongs motion. This expanding device isslidingly pivoted at 33 to a guiding and supporting plate 34, whichextends upwardly from the rear of the platen frame 3. Floating pivots 35of the expanding device 32 are yielda stud 40 ex-'-Q5 rear end of thecollating frame 26 is caught onto the cross-bar 41 by means of a pair ofhooks 42provided on the cross-bar 41, and

extending through openings 43 provided on the tail end of the collatingframe 26. spring 29, through the lazy tongs 32 and the cross-bars 39 and41, normally exerts a pull on the tail end of the collating frame 26, soas. to hold the latter taut.

The action of the spring 29 is opposed-by a second spring 43*, whichtends to extend a second expanding device 44 in a manner similar to thefirst expanding device 32. The second expanding device 44 is'eonnectedto the leading edge of the collating frame 26. This connection includesa cross-bar 45, located in back of a supporting and guiding plate 46,extending up from the front side of the platen l'and supported by theplaten fran'ie 3. The guiding plate 46 is provided with a slot 47,through which extends the moving pivots of the expanding device 44. Thecross-bar 45 is also connected to this slot 47- through a frontcross-bar 48 by means of a pin 49. The cross-bar 48 is located in frontof the plate 46, and is provided with The hooks 50 to extend throughopenings v51 in the leading edge of the collating frame 26, and therebysupport the collating frame. Inasmuch asthe first spring-actuated e!panding device draws on the tail end of the collating frame 26, and thesecond springactuated expanding device draws on the accuses Leading edgeof the collating frame 26, the frame will be held tight on the platen 1,and the free ends thereof, which extend from the platen, will be heldtaut. For the purpose of maintaining the col' lating frame always in thesame relative line-space positions with respect to the platen, or inother words to prevent slippage, as the collating frame moves back and 0forth with the rotation of the platen, a pinand-sprocket arrangement isprovided. This includes pins 52 located on both ends of the platen 1 ina circular series, so as to form sprocket wheels, which engage inperforations 53 provided on both sides of the collating frame 26. Inthis way, the position of the collating frame will be justified and theline-space intervals always maintained in corresponding relation withrespect to the platen 1.

After the sheets are assembled on the collating frame the platen isrevolved backwardly or reversely to carry them around to their startingposition To enable this reversal to be easily done, the pressurefeedrolls 10 and 1.1 are released, and the detent 7 is withdrawn. fromengagement with the line-space wheel 6 by an operation of either thefinger-piece 14 or the hand-lever 21. The spring or driver 29 nowbecomes effective to feed the collating frame backwardly to introducethe work-sheets into the machine. The releasing mechanism isautomatically tripped When the collating frame reaches a positioncorresponding to the proper placement of the work-sheets on the platenafter they have been assembled. This is done automatically by anadjustable stop or trip 54 provided on the collating 40 frame 26. Thetrip 54'may be secured in any one of a number of holes 55, so as tovarythe instant of its action, and thus make its action correspond with theparticular requirements of the Work being collated. The

trip 54 travels around rearwardly with the collating frame 26 until itcomes into enagement with an arm 56 on a bell crank 57. Then the trip 54will rock the bell crank 57, so as to force an arm '58 on the bell crankagainst one of the arms of the hand-lever 21. The hand-lever 21 isrocked from the position shown in Fig. 3 to the position shown in Fig.4, thereby restoring the detent '7 and the presspre feed-rolls 10 and11.

55 After this latter action has taken place, the collating frame ispositively arrested by the stop 54 cooperating with the arm 56.

When a new piece ofwork is to be done, I)

the parts are adjusted to the position shown 6%) in Figs. land 2, toenable the work-sheets to be easily collated. The work-sheets 27,

' with. the interleaved carbon sheets, are then collated by beingimpaled on the studs 28 in the various relative positions desired, soas. as to have the desired lines thereon in regisof the platen 1, so

ter with each other, although these lines may not be at the samerelative positions on the several sheets. After the sheets have beenassembled or collated, the release key 21 is actuated, thus renderingthe spring 29 effective to reversely rotate the platen, and it willcarry the collated work-sheets, bottom edge first, down around theplaten until the trip 54 comes into engagement with the arm 56 and bellcrank 57. Then the trip 54 will first unlock the releasing mechanism,enabling the detent 7 and the pressure feedrolls 10 and 11 to return totheir active positions. The trip 54 thus limits the return movement ofthe collating frame 26 by causing the detent to arrest the reverserotation that the initial position of the collated work-sheets for thefirst line of writing is automatically determined. This may be chan edas desired to suit the charactor of wor by adjusting the trip 54 in anyone of the openings 55. When so positioned, the work may be written lineby line until completed, the frame 26 traveling in synchronism with theplaten 1, inasmuch as it is positively geared thereto by means of thepin-and-sprocket arrangement 52, 53. The rear support 34 will keep anyworksheets from dropping off the studs 28, especially any that extendonly part way across the platen. When the work is completed, it can bedetached from the studs 28 and a new set of sheets collated or assembledon the collating frame 26. During the back and forth movement of theframe 26, the springs are maintained taut and the work sheets heldsmooth in all positions of the latter.

The collating frame may be readily detached from the machine andreplaced by another having its rows of collating studs spaceddifferently apart, as it may sometimes be desired to collate sheets withdif; ferent distances between rows of perforations or collating holes.The collating frame is detachably be conveniently replaced since itbecomes worn by the frequent hammering of the type-bars, if it extendsacross theplaten and serves as a backing for the work-sheets.
